custom styles not working

[natashache]

It seems setting custom styles doesn't do anything to the styles of the rendered object. Here's my code:

                <View style={[styles.section, { paddingTop: 31 }]}>
                      <RNDraftJSRender
                        contentState={JSON.parse(soundcast.long_description)}
                        customStyles={customStyles}
                      />
                </View>

where

        const customStyles = StyleSheet.flatten({
          link: {
            color: 'blue',
            fontWeight: 'bold',
          },
          paragraph: {
            fontSize: 14,
            color: Colors.fontBlack,
            fontWeight: 'normal',
            letterSpacing: -0.65,
            lineHeight: 14,
          },
        });

No matter how I changed the customStyles, the rendering doesn't change at all.
